I can't believe how clueless so many people are. TJax isn't a good QB yet, but he's shown flashes of greatness. He nearly singlehandedly brought Minnesota back against Denver in the final game(probably would have if Troy Williamson had glued some velcro to his chest). That was a game when Minny's running game was going nowhere.
Some of these responses: Cleo Lemon? Really? The same Cleo Lemon that couldn't beat out John Beck for a job? Culpepper? His days are done, sorry to say. Same with Pennington. Couldn't take the chance that his shoulder would continue getting worse.
In my mind, there are two backups who would start over TJax and one that might.
Kurt Warner. He still has the gun and has enough understanding of the game. Clearly better than TJax, but is old and wouldn't be a viable franchise QB.
Billy Volek. Has shown great poise when he's gotten playing time. Would be an upgrade as of now, but TJax has more raw talent than Volek ever will.
Maybe.
Sage Rosenfels. Was good last year in fill in duty, but since the Texans felt they needed to trade for Shaub when they still had him on the roster I doubt his overall talent.
I haven't been a huge fan of TJax ever since I said "Who?" when they drafted him. However, I feel that he has the talent to become a great QB. I wouldn't take any so-so player over him because a mediocre backup will never be more than mediocre.
